SFEUIFIGATION forming part of Letters Patent No. 649,917, dated May 22, 1900.

Application filed October 11,1899. Serial No. 733687. (No model.)

To ztZZ whom it in-rt concern.-

Be it known that we, HENRY O. Donnson and DAVID W. Cnnnsron, citizens of the United States, and residents of Nyack, in the county of Rockland and State of New York, have invented certain new and useful Improvements in Electric Shampooing Apparatus, of which the following is a specification, reference being had to the accompanying drawing, forming part thereof, in which similar letters and figures of reference indicate corresponding parts.

This invention relates to an improved elec-' tric shampooing apparatus, the object thereof being to provide an efficient means for applying a current of electricity to the scalp of a person by the agency of a barber or other operator while treating the scalp of the subject for the purpose of strengthening, drying, and assisting the growth of hair.

The invention will be hereinafter fully described, and specifically set forth in the annexed claims.

In the accompanying drawing our invention is illustrated by a single diagrammatic view shown partly in perspective.

In the practice of our invention we employ, primarily, a barbers chair-A of adapted contour and construction. Upon each arm of the chair is placed a metallic plate a, composed of Zinc or analogous metal. These two plates are in electrical connection with an ind uctioncoil B by means of a wire conductor I), having branches 1 and 2 leading, respectively, to the plates at and in electrical connection with said plates. Leading from the opposite pole of the induction-coil B is awire conductor 0, which has extended branches 0 and c, having zinc bracelets D attached to their respective ends. These two branches are nor- 7 mally suspended from a hook (I, which is seof wire conductors e and e, and a switch F is interposed between the batteries and the induction-coil for the purpose of turning the current off and on as the operator may desire.

The induction-coil I is provided with an ordinary sliding rod Z)" to be employed for the purpose of graduating the intensity of the current.

In the operation and use -of the apparatus the subject to be operated upon sits in the chair A and places each hand upon a plate C6. The operator then adjusts the bracelets D to his respective right and left hand wrists and turns on the current at the switch F. Then by contact of his hand with the scalp of the patient a circuit is established and the electric current is communicated to the scalp of the patient for the purpose of treating him in a manner well known in the art of applying electric currents. hen the treatment is completed, it is simply necessary to turn off the current at the switch F and hang the branches 0 and c of the conductor C over the hook 61!, thus placing the apparatus in a position for the reception of another patient.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. As an apparatus for applying a current of electricity to the body, the combination of an induction-coil, a source of electrical sup ply and a chair having metallic plates thereon for contact with a patient, the indnctioncoil located between the source of supply and the chair and being connected electrically to the said plates by means of a conductor, and a conductor connected to the other pole, having bracelets thereon for engagement with the arms of an operator, whereby the circuit may be made by contact of the patient with the said plates and the operator, substantially as shown and described.

2. In an electric shampooing apparatus, the combination of a source of electric supply, an induction-coil, and a chair having contactplates thereon, and a conductor in electrical engagement with said contactplates through the medium of one pole of the battery, and a conductor having bracelets thereon, in conpresence of two witnesses,this 9th dayof Octonection with the other pole of the battery, ber, 1899.
